PATENT GFFICE.

RESPIRATOR AND INHALER.

SPECIFICATION formingpart of Letters Patent No. 781,516, dated January 3 1, 1905. i Application iiled February 3, 1904. Serial No. 191,779. n

To all whom t may concern: Y

Be it known that I, GEORGE N. GUTHRIE, J r., a citizen of the United States, and a resident of Cookville, in the county of Putnam and State of Tennessee, have invented a new and Improved RespiratorA and Inhaler, of which the following is a full, clear, and exact description. Y My invention relates to respirators and inhalefrsffor attachment to the human face Ain order to permit the subject to breathe air from other rooms or purified air and prevent inhaling of undesirable gases and vapors.

The objects of my invention are to provide such inhalers and respirators with devices for purifying the air, removing'solid matter therefrom, and for conveniently connecting them to such purifying' devices or to the outside air. Reference. is to be had to the accompanying drawings, forming a part of this specification,

` in which similar characters of reference indicate corresponding parts in all the'figures.

FigureA 1 illustrates one form of my invention applied to the human face. Fig. 2 is a bottomview of the sameA form of my invention with parts in section. Fig. .3 Vis a sectional view of the same on the line 3 3 of Fig.

^ 2. Fig. 4 is a cross-sectional view of a detail.

of my invention, and Fig. 1() is a sectional" view taken on a horizontal line below the nosepiece in Fig. 9. A

l representsanose-piece provided with a wire 2 atits edge surrounded by the material of the nose-piece, which may befrubber or other flexible oruniiexible material.

nose-piece is adapted to be held upon the face by holders 3,V similar to those.- used in spectacles, as shown. It is also provided with tubes 4 4 for connection with the purifying attachment or with pipes leading to the outside air.

5 represents one form of purifying attach- Fig. 9 is-a sectional view similar to The ment which comes within the scope of my invention. This form has a rubber or other lining 6 within the metallic sleeve 5 and is provided with small hairs or follicles 7, eX- tending radially from the internal surface toward the center. This devicemay be used without the liningk 6, and it ma'y be attached to the connections from the inhaler at any point, as desired. (See Fig. 6, for example.)

To the tubes 4'ma'y be attached tubes 8, having branches 9 and 10, the branches 9 being for exhalation and the branches 10 for inhalation. Both these branches should be provided with very light and easily-operated valves 11 and 12, one opening outwardly and the other inwardly, as shown, so as to automatically provide for the operation of the device to cause the air to be'drawn inthrough the branch 1 and forced, out `through the branch 9. To the branch l0 may be attached by tubes 14 a second branch tube 13, and said latter tube is preferably also attached to a tube 15, adapted to communicate with a main 16'or with the outside of the building. Instead ofsaid tube communicating with the outside of the building it may be attached at any point to a shorttube 17, fitting within the top of a casing 18, which is provided with a {ine-wire sieve or strainer 19, and also has one or morecompartments filled with sponge or other eiicient straining device` 2O or 21. v vided in the bottom of the casing and a pasfsage-22 to the upper sponge 20.

attached to branches26, leading therefrom to the main pipe 15 or to any ofthe other devices shown. 27 (shown in dotted lines in Fig. 8) is a passage which may be'formed between'thenose-piece and the mouthpiece. The parts 25 26 may be connected with the other parts (shown in the other lfigures) in the same manner as the parts 8, 13, and 14. 28 is a wire extending from the mouthpiece and adapted to be held between the teeth 'to support the device. i Usually one of the supports 3 or28 will bev sufficient, but they may both be used, if desired.

An opening 23 will of course be p ro- IOO , connected up as desired to the outside atmosphere or to the puriliers 5 or18. Usually both puriliers will not be needed, but they may be used in combination, if desired. The inhaled air passes through the main 16, or the purifiers 'or 18, the tubes 15, 13, and 14., the branches 10 of the tubes 8, to the tubes S and to the nose, and through the tubes 25 and the branches 26 to the mouth.

My invention is capable of universal use and may be attached to any subject, being made in various sizes. It can be litted up in various ways and the purifiers applied so as to make it useful under all conditions. One way in which I have contemplated applying it is to secure a tube to a [ire-hose throughout its length, providing valve-openings in the lire-hose at numerous points in order that the lace piece and tubes may be attached thereto at any desired point. This will insure communication with the outside air at all times.

My device is light and simple in construction, it is inexpensive, and it prevents air from entering the lungs except through the filtering medium. It does not permit the exhaled air to be rebreathed, it is not likely to become clogged, and is of goed appearance.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In an inh aler and respirator, a nose-piece, a tube extending therefrom, a conductor from said tube to the open air, an air-purier attached to said conductor, and an air-straining device within said conductor comprising inwardly-projecting hairs.

2. In an inhaler and respirator, the combination of a nose-piece, a tube extending therefrom, a conductor from said tube tothe open air, an air-puriiier attached to said conductor,

a mouthpiece attached to said nose-piece and provided with means for conducting air thereto and therefrom, and a passage between said nose-piece and mouthpiece.

3. In an inhaler and respirator, a mise-piece` a tube extending therefrom, a conductor from said tube to the open air, an air-purifier attached to said conductor, a n'iouthpiece, and means for holding said mouthpiece in position, adapted to be held between the teeth.

4. In an inhaler and respirator, the combination of a face-piece, a tubular conductor extending therefrom, and an air-strainer in said conductor, comprising inwardly-projecting hairs.

5. In an inhaler and respirator, a face-piece, a plurality oi' conductors leading therefrom, a branch in each conductor lor exhalation, a valve in each conductor, a valve in each ol said branches, and a main conductor conneetml -nose and mouth piece constituting a lacepiece, a plurality o1 conductors leading therefrom, a branch in each conductor for exhalation, a valve in each conductor, a valve in each branch, and a main conductor connected with all of said conductors leading lrom the face-piece to the open air.

In testimony whereotl I have signed my name to this speeilication in the presence of two subscribing witnesses.
